Homewyse estimates the cost to replace an electrical outlet as between approximately $140 to $210, as of 2015. Some problems don't require a replacement, while others might indicate a bigger problem within the electrical infrastructure.
Wall outlets are designed to carry a significant amount of electricity and withstand regular use, so they are designed and built with durability in mind. However, power spikes and physical damage can cause an outlet to stop working, and the high amount of current the system can draw makes proper safety essential before attempting a repair. Homeowners with the right tools and proper safety equipment may be able to fix an outlet if the problem is relatively minor.
